G'day Peter, I have a medium size impact mill which will crush down to -5mm...at this stage it has always been run dryand the plan is to 'add water' between the impact crusher and the ball mill....which will run wet.Just wondering if people have run one wet before....is it design sensitive??? I guess the material running will always have an effect on if things bog down or not as well. Easy thing is to shove a hose in the top and see what happens but I prefer to get peoples opinions where possible.

I had a little rotary chain crusher and all ways had it running dry, one day I put the hose in the top and see how it went. Two things I liked about the water was no dust and second the noise was suppressed a fair bit. The bad side was I did not keep the water contained to reuse and could of lost a lot of flour gold as my brother showed me, you don't see that stuff to well with all the frothy coming out the crusher, but learnt my lesson
